Thank you, Mr. Arnold.
I've noticed, by the way, colleagues, that we've been very good at identifying who the question is directed to. That's always a good thing, of course, when you have someone in by video conference. Thank you for that. Just as a reminder, please, that goes a long way in putting the question, especially in Dr. Ban's case.
We're going to Mr. Stetski, please, for seven minutes.
